removeprefix() was added only in 3.9. As long as the "jso_sub_" prefix is
always going to be there anyway, switch to a less specific but more
compatible construct.
Fixes: f6c6f2679d49 ("libxl: libxl__object_to_json() to json-c")

Sadly this is only the tip of the iceberg. Some minimum version of the
json-c library is apparently needed for the toolstack to build, but no
minimum version is being checked for.
